Canberra's main drag was a leafy-green festival of foliage before being turned into a barren stretch of cement and construction detritus to make way for the light rail. So what happened to those trees?

ACT planning authorities have made the "unprecedented" decision to revoke a development application approval they gave more than a year ago, after an internal review found it should never have been given the green light in the first place.

One of the biggest supporters of the light rail project in Canberra has joined a chorus of concerns about the Government’s preferred route for Stage 2 to Woden though Parkes and Barton in order to service their tourism and employment centres.

A concept plan for a Canberra to Eden railway line has been labelled "visionary", and something that would allow the capital to unlock the potential of "relatively isolated" areas in south-east Australia and become the region's freight hub.

A former ACT government adviser and property industry lobbyist has hit out at the proposed route for the second stage of Canberra's light rail, saying the Barton detour would undermine the entire future network.

Track preparation and testing are now underway on Stage 1 of Canberra’s light rail network, in preparation for its opening at the beginning of 2019.

For the rest of 2018, track preparation and testing will commence from 6:00pm to 6:00am Sunday through to Thursday with occasional Friday night and Saturday night works to be expected. Carrying out the testing process at night will enable construction works such as landscaping and building the light rail stations to continue during the day.

A new suburb planned for Canberra's north could heighten the risk of flooding along a section of Canberra's light rail route that was inundated during a one-in-100-year weather event earlier this year.
